Seems a reasonable idea. DTM has been in Finland in 90s and with emphasis on 'internationalisation' going to a new circuit in Finland could be a possible solution. What I wonder about is whether DTM could attract many people there.

Well I thoroughly enjoyed it The cars are impressive enough to watch to compensate for a lack of overtaking - walking around the circuit and watching how they take the various corners (and the differences in the way each make performs) kept me busy. Seriously impressive.
